Shengya A-203GS Pure Class A intergrated amplifier Full balance hifi Audio Power amp 100W*2
come with remote control Brand new

It is an intergrated amplifier, it is a hifi audio power amp too.
come with a remote control



a) One group of audio signal input terminal (LINE 5) is used to connect an external preamp audio output terminal , so that the machine can be used as a pure power amp.A-203GS Class A amplifier adopts fully balanced amplifier circuit,which ensures an excellent sound quality, tone and sound field.
b) The core of preamp section uses high-speed DC amplification module chip,which has an outstanding performance in a wide frequency response, low distortion, slim thick tone and active dynamic vast. Volume is controlled by  electronic volume control chip CS3310 produced by American Crystal Company, so that the error between the channel level control is within 0.5dB.
c) The machine is equipped with a shielding box transformer, which is throughout the epoxy resin filling, effectively reducing the work produced by the transformer.Two-channel audio using special filter capacitor , with a total capacity of up to 120,000 microfarads and 32 high-power transistors to form a 100W class A output stage ,and sound performance is delicate.
d) Adopts a dedicated film capacitors of audio MKP ,with 1% precision metal film resistors and precision power supply in parallel. The signal of power amplifier is from the input circuit composed of FET cascode differential amplification , famous transistortube for the second voltage amplification and the differential current drive.
